Congrats to the Hacktoberfest Open-Source AI Challenge Week 4: Ghost in the Machine Winners! - DEV Community

Posted on Nov 13 • AI-assisted
Digital ofrendas and dead code séances won
The results are in for the final week of our Hacktoberfest DEV Challenges! For Ghost in the Machine, we asked you to build something spooky, or something that honors the past in the spirit of Día de los Muertos, with open-weight models or open-source AI.
You took the theme in every direction we hoped for, and plenty we didn't see coming. We saw digital ofrendas, ghosts of forgotten repos, and séances for dead code. Many of you showed exactly why open innovation matters here: family stories, inboxes, and photos that never leave your own machine.
Thank you for your patience while we reviewed every submission, and thank you to everyone who built with us this week and all month long. Now, let's celebrate our winners!
